Abstract
In the plastic hot processing industry, plastic particles to be processed are generally directly added into an extruding machine to process at normal temperature, so that the initial temperature of the raw materials is completely determined by the environment temperature, and the humidity environment of the materials is completely determined by the environment. With the advancement of the plastic processing technology and the appearance of certain special functional plastics, the existing processing technology cannot reach the corresponding product quality; in addition, as the initial temperature and humidity cannot be controlled, the repeatability is bad. The utility model provides a plastic extruding machine with a raw material preheating device, wherein a heating iron hoop on the raw material preheating device is used for heating, and the temperature and the humidity are monitored by a temperature sensor and a humidity sensor. A stroke switch is arranged at the lower end of the raw material preheating device; the stroke switch is turned on and plastic enters a feeding hopper after the raw material preheating device heats for a period of time according to the temperature processing technologies of different materials. The plastic extruding machine is provided with the raw material preheating device and has a temperature and humidity monitoring function, so that the quality and repeatability of the plastic processing products can be guaranteed.
Description
Technical field
The utility model relates to the plastic hot manufacture field, relates in particular to a kind of plastic extruder that has the raw material preheating apparatus.
Background technology
In the plastic hot processing industry, generally plastic grain to be processed is directly joined in the extruder at normal temperatures and process, extruder and barrel configure suitable processing temperature in advance.This processing method makes raw-material initial temperature depend on environment temperature fully, and the humidity environment of material also depends on environment fully.Along with the progress of plastic processing technology and the appearance of some specific functionality plastics, existing process technology does not reach corresponding product quality, and because initial temperature, humidity are uncontrollable, poor repeatability.
The utility model content
The utility model is to the deficiency of prior art, a kind of plastic extruder that has the raw material preheating apparatus.
Described plastic extruder comprises frame, is located at machine barrel, reduction box, drive motors, screw rod, loading hopper on the frame.Screw rod is positioned at machine barrel, and an end links to each other through shaft coupling with the output shaft of reduction box.
Described loading hopper top is equipped with the raw material preheating apparatus.Wherein, the heating iron hoop is installed on the raw material preheating apparatus, its inside is equipped with temperature sensor and humidity sensor.
Described raw material preheating apparatus lower end is equipped with travel switch.
A kind of plastic extruder that has the raw material preheating apparatus that the utility model provides heats through the heating iron hoop on the raw material preheating apparatus, carries out the monitoring of temperature and humidity through temperature sensor, humidity sensor.Raw material preheating apparatus lower end is equipped with travel switch, and according to the temperature processing technology of different plastics, the raw material preheating apparatus is opened travel switch after heating a period of time, and plastics get into hopper.The plastic extruder that the utility model provides has guaranteed the quality and the repeatability of plastic processing product owing to have the raw material preheating apparatus and the temperature and humidity monitoring.
